Month by month
The stock's clearest edge over the S&P 500 lands in November (+12.8 pts); it has trailed the market most in April (−11.9 pts).
“vs S&P” is Clearwater Analytics Holdings Inc’s average for a month minus the S&P 500’s average for that same month — isolating Clearwater Analytics Holdings Inc’s own seasonal edge from broad market drift.
Reality check
Over the last 4 years, August has closed higher 100% of the time versus 100% across the last 5 years — the pattern is holding.
Figures are the typical (median) August return and how often it rose — the last 4 years versus the last 5(the heatmap’s default window). This verdict stays anchored to that 5-year window even if you zoom the chart, so it never disagrees with the badges above.
In plain English
Strip the year back and a single month does the heavy lifting: August, up in all 4 Augusts while the other eleven tend to blur together.
The headline flatters a touch — its +9.1% average sits well above the +5.3% a typical year delivers, the work of a few big Augusts. That reliability comes with real swings, mind — even August ranges by 8.5% from year to year, so any single year can land far from the average. Crucially, the gain is the stock's own rather than a rising tide's: August has cleared the S&P 500 by +8.8 points above the index. That consistency sets it apart from the field, where the average stock manages August only about 52% of the time.
The strength clusters rather than stands alone — July–September forms a firm stretch that carries much of the year. The weaker half of the year is plainer: April has been the soft spot — the weakest of 6 months that average a loss (−10.2%), and the edge isn't year-round — the stock has trailed the S&P 500 in April, June, and January. Its roughest month on record was a −23.2% May in 2022 — a reminder of how hard even a seasonal name can fall.
The takeaway is less about when to buy than what to expect: August aside, the stock's months offer little reliable tilt. With a short 5-year record, the signal is best held loosely.
Short answers on the stock's best month (August), its worst (April), and whether it really trades seasonally.
Yes, to a pronounced degree. Since 2021 its best month (August, +9.1%) has run well ahead of its worst (April, −10.2%) — the heatmap above shows how steady that gap has been year to year.
August has been the strongest, averaging +9.1% and closing higher in all 4 years on record since 2021.
It's the weakest, averaging −10.2% — historically a soft spot, though it still varies from year to year.
